Tire Decision - Michelin Pilot Sport 4S vs PS2

Turbo has a front weight bias vs. NA C2 so with stiffer walled N3's I run 36 front and 40 rear for the best performance. Tried many pressure combinations, higher rear pressure gets squirmy. Two 911 friends preferred the N3's to the 4S's.

I don't know why everyone falls for the N rating BS. The PS2 sidewall isn't much stiffer than any of the other Michelin's. If you want a stiff sidewall go Pirelli. The different tires and N rating primarily changes the rubber compound across the tire contact patch and has little to do with sidewall stiffness or overall tire construction. You should be running 36/44 PSI cold if running 18" staggered if not that could be your issue. The tire will get squirmy if you run lower pressures that is on the street of course.
Here is cross section of an identical tire, the only difference N-spec vs not. It is the same size and model (though I can't recall which).
Beyond a potential compound difference which can't be seen, visibly you can see the shoulder/sidewall is different and additionally you can see the N-spec has additional reinforcement. N-spec's are on the left.
BTW, I have no dog in this fight. I have 3 sets of wheels with 3 different tires. Michi PS4S, Michi PS2 N3, Pirelli P-zero's. All will get me to Starbucks in record-breaking times.

The "N" issue was perhaps pertinent when the 993's frst appeared, decades ago, and tires, Michelin and whatever, were far different than now. Rubber coumpounds and sidewalls have all evolved. I think co-branding with Porsche was very clever marketing, and it paid $$ in profits for Michelin, still does for some buyers. Conti Extremes work great, are cheaper, and seem to get better treadwear.

For the 993 I absolutely love the PSC 240.

What does 'staggered' mean in this context "You should be running 36/44 PSI cold if running 18" staggered" thx

Marked tyres incorporate the DNA of individual brands and models as a function of the performance brief and requirements specified by each manufacturer. The fitment of manufacturer-approved tyres ensures an optimal driving experience, from superior handling and ride comfort to reduced noise and even more enjoyment behind the wheel.
Marked tyres are a sign that they comply with all of the car manufacturer's requirements. It is important to know that all OE tyres are approved by the manufacturers that fit them. When replacing them, it is therefore important to specify the same tyre as that approved by the car manufacturer.
